EN | 5 Intellivox DDC | Installation Manual | Introduction 1. Introduction. This paper describes the factory recommended installation procedure for the Bosch Security Systems’ Intellivox range of controlled loudspeaker-arrays. This type of loudspeaker-array is equipped with an onboard Digital Signal Processor (DSP) module. This manual describes mechanical matters like mounting hole positions and outlets for cable feed-through, as well as information for wiring of the connectors.
Intellivox DDC | Installation Manual | Installation Guide 2. Installation guide This chapter deals with the practical aspects of installing the Intellivox loudspeaker column. • SI units are used as a default, all mentioned dimensions are stated in meters or millimeters. • Unless stated otherwise, column dimensions refer to the standard Intellivox-2c, which has the electronics module mounted at the low end of the enclosure.
Intellivox DDC | Installation Manual | Installation Guide A simple surveillance function may be realized by means of the ‘failure detect’ connection in case the RS485 network interface is not used. Three relay contacts, ‘normally open’ (NO), ‘normally closed’ (NC) and ‘common’ (COM) are available on this connector. If the autogain function of the Intellivox is used, a separate ambient SPL/temperature sensor has to be installed and connected.
EN | 8 Intellivox DDC | Installation Manual | Installation Guide 2.3 Wiring and connections. 2.4 Signal connections. 2.3.1 Mains power. • Be sure that the mains voltage stated on the unit complies with the local standard before connecting the Intellivox to the mains supply. All signal connections are realized by using WAGO series 231 cage clamp connectors. A major advantage of these connectors is the fact that the connector can be fitted without the need for soldering.
Intellivox DDC | Installation Manual | Installation Guide Fig 3 • Intellivox connector block. A removable panel on the front side of the Intellivox (backside for the Intellivox-1b) allows all connectors to be inserted when the unit is already mounted. EN | 9 should be completely covered by the blade of the screwdriver (refer to Fig 4 which shows the internal clamp construction). 5. Push the screwdriver to open the cage clamp, this may require some force.
EN | 10 Intellivox DDC | Installation Manual | Installation Guide 2.5 Methods for mounting the Intellivox. 2.5.1 General. For mounting of the Intellivox column there are two or three attachment points (depending on the model) each consisting of four threaded inserts at the rear of the enclosure. One point is located at the upper side, the other near the bottom and the third, if existing, at the center position. The column should be mounted using both locations.
EN | 11 Intellivox DDC | Installation Manual | Installation Guide hexagonal nut. The swivel brackets are mounted to the rear of the enclosure by four M5 pan head screws (factory supplied). Refer to Table 4 in chapter 3.1 for ordering information. 3. The third method is to mount the column directly to a wall or a dedicated mounting panel by means of spacers and screws through the mounting surface.
Intellivox DDC | Installation Manual | Installation Guide columns can differ substantially from the 2c model. Mechanical drawings of the other models can be found in chapter 3.5 or in the respected datasheet. Fig 7 - The LBC 3253/00 dimensions are shown, including the vertical spacing between the upper and the lower bracket as well as the vertical offset of the acoustical reference. 2.5.3 Mounting procedure.

EN | 14 Intellivox DDC | Installation Manual | Appendix The AGND pin serves as a reference for the SPL and temperature measuring input circuitry. To keep this ground signal as clean as possible, the AGND wires together with the MIC and the NTC signal should be run through a shielded cable. The shield should be connected to the GND pin of this terminal block. • AGND should not be connected to any other ground pin (GND or DGND) on the chassis. Fig 8 Ground configuration of the Intellivox chassis.
Intellivox DDC | Installation Manual | Appendix Although in terms of safety and immunity this is the most preferable set up, an unwanted ground loop is created which can cause audible noise or hum. The appearance of this effect is strongly depending on the cable routing, the design of the grounding scheme and the existence of local magnetic fields (caused by power transformers, railway chopper supplies etc.).
Intellivox DDC | Installation Manual | Appendix EN | 16 In order to restore the galvanic safety path of the signal wiring up to a certain level, it is possible to connect a 100 OHMS 1W resistor parallel with the 100nF capacitor. The isolation of the low frequency ground loop is partly canceled by this resistor, but the reduction of the induced noise can still be sufficient while at the same time some of the benefits of the original concept are restored. A diagram of this solution is shown in Fig 12.
Intellivox DDC | Installation Manual | Appendix Fig 13 Optional high frequency decoupling for 70 V / 100 V systems. Conclusion: Because the Intellivox can be a part of a complex installation it is impossible to prescribe a fixed grounding strategy that will perform best in all situations. Safety, immunity and reduction of emission are very important issues that should always determine the ground configuration that is applied.
Intellivox DDC | Installation Manual | Appendix Network configuration. A network is composed of one master device and one or more slave devices. A master device can exist of a PC running the RS-485 network WinControl software and a RS-232 to RS-485 converter. All slave devices are wired in parallel, the master device is connected with the AB and YZ terminals interchanged (see Fig 14).
EN | 19 Intellivox DDC | Installation Manual | Appendix Master device As mentioned before the RS-485 network concept needs one master device. This master device (network controller) is composed of a PC running WinControl and a RS-232 to RS-485 adapter connected to the RS232 port of the PC. Detailed information about the WinControl program can be found in the related help file. The RS-232 to RS-485 adapter is a small 9-pin sub-D device which can be connected to one of the computer’s serial COM ports.
EN | 20 Intellivox DDC | Installation Manual | Appendix Notes for type RS-232 to RS-485 adapter: • Both ends of the RS-232 to RS-485 connector have the same 9p female sub-d connector. Be careful to install it in the proper way. • The +9 V (pin 9) at the RS-232 side of the adapter should be connected to an external + 9 V / 50 mA DC power supply in case the power delivered by the PC (RTS or DTR) is insufficient. This might be the case with large cable lengths.
